803M/MH / 853M/MH / 859M/MH

OUTRUN

EXPECTATIONS.

When we designed our next-generation 800M- and 800MH-Series machines, we relied on the input of the people who run them every day. These job-proven midsize models have been redefining uptime, productivity, and low daily operating costs — in the woods and at the landing — because you wanted them to.

THANKS TO YOU, these tracked feller bunchers and harvesters are outrunning expectations — again.

4

Reach beyond

New extended stick option (for 800MH models only) enables a longer reach to minimize the number of cut trails and maximize machine efficiency.

Multiple boom-set/ attachment combinations

A variety of boom sets and felling and harvesting attachments can be combined to optimize productivity across a wide range of conditions.

Surefooted stability

Long, wide undercarriage provides solid balance to maximize stability, no matter the terrain.

Get in the swing

Dual swing system increases power and performance in demanding felling or harvesting conditions, boosting overall productivity.

Ample tractive effort

Strong tractive effort generously increases capability for negotiating difficult or steep terrain, deep snow, and swamps.

Smart debris management

Designed to keep your workspace free and clear, the productivity-boosting debris-management system is integrated into the hood and left-side guarding to prevent materials and debris from entering the cooling package. External screening, sealed cooler compartment, and standard variable-speed reversing fan provide cooling protection when and where it’s needed.

YOU ASKED FOR IT

Built for the way you work.Ongoing input from Customer Advocate Groups (CAGs) helps make 800M- and 800MH-Series machines even more rugged and reliable.

Adaptable to preferences and environments

RCS can be tailored to individual skill levels and specific harvesting conditions, from large single-tree harvesting to high-speed, multi-stem cutting.

Operator-specific settings

Multiple RCS settings can be saved according to individual operator preferences. Novices may prefer a slower, more methodical pace, while highly skilled pros may want faster response.

Selectable operation

Press a single button to engage RCS mode. Conditions don’t suit the fast, parallel motion of the boom? Turn RCS off with another touch of a button.

MAXIMIZE PRODUCTIVITY

Rapid Cycle System.Faster, low-effort joystick control of all boom functions helps operators of 800M- and 800MH-Series machines be more productive. Rapid Cycle System (RCS) combines automated felling-head arm cycling with simple boom control — dramatically reducing operator fatigue while increasing efficiency and productivity.

FT4 IN THE FOREST

Cutting-edge solutions.

You asked for the latest technology to meet FT4/Stage IV emission regulations, and we listened and delivered. In fact, we’re always focused on implementing the right engine solutions at the right time — without compromise of power, reliability, or ease of operation.

Fluid-efficient FT4 engines

Our FT4/Stage IV PowerTech™ PSS diesels meet emission regulations without sacrificing power or torque. Built on our EPA Interim Tier 4 (IT4)/EU Stage IIIB solution, this simple technology delivers a winning combination of performance, fluid efficiency, and reliability.

Minimal impact on operation

Under normal operating conditions, the engine’s natural heat breaks down trapped particulate matter and cleans the exhaust filter without impacting machine operation. Ash-service intervals for the diesel particulate filter (DPF) are condition based, meaning machine alerts will notify the operator before service is required. Typically, ash service is not necessary until the first engine overhaul depending on machine application, regular maintenance practices, and type of lubricating oil.

Low total fluid consumption

John Deere FT4 engines maintain peak engine performance while minimizing total fluid consumption — diesel fuel plus diesel exhaust fluid (DEF). This exceptionally conservative DEF-use rate is up to four times lower than that of some other FT4 systems.

OPERATE IN COMFORT

Room with a view.

Spacious operator station was designed by loggers for loggers. It’s roomier and more comfortable, with ergonomically designed controls. And the view has to be seen to be believed, with significantly more window area, for improved visibility.

10

Low-effort control

Fully adjustable armrests enable fingertip control of all machine functions on tracked feller bunchers; on tracked harvesters keypads are mounted on the joystick. Fully adjustable air-cushioned seat provides outstanding daylong comfort in the

climate-controlled cab.

Sealed-switch module

Sealed touchpad keeps out dust, moisture, and debris, minimizing wear. Proven marine-grade control center eliminates rocker switches, numerous wires, and unsealed connections, and lasts up to 10 times longer than standard dash switches.

Expansive visibility

Floor-to-ceiling front window, large side windows, skylight, and optional floor window (standard on levelers) significantly expand the view of the harvesting area and the work at hand.

In the woods, uptime is the name of the game. That’s why we went to our toughest customers, loggers just like you, to continually reinvent the rugged 800M- and 800MH-Series Tracked Feller Bunchers and Tracked Harvesters. Your latest great idea is a new extended stick option on 800MH models.

EXPECT MORE

And then some.

More boom

Field-proven boom design is transplanted from our larger 900M- and 900MH-Series models. All booms are robust, with thick plates and strong joints, for extended durability and wear life. Designed for use with smaller attachments, the new extended stick option (only on 800MH models) reaches 9.9 m (32.5 ft.) and features a narrow boom tip to extend past standing timber and cover wider swaths, minimizing damage to harvested trees and easing travel in sensitive areas.

Stable and able

Reliable stability and solid engine horsepower help make quick work of the woods in all conditions.

Larger fuel tanks

Fuel-tank capacity has been increased (to 230 gal. versus 154 on comparably sized machines) to extend intervals between fill-ups.

Through-nose harvester-head plumbing

Through-nose plumbing option routes hoses up and out of harm’s way to extend hose wear life, increasing uptime and reducing operating costs.

Optional closed-loop hydrostatic drive

Boost multifunctioning, particularly on slopes and in rough terrain. Adjust priority between track drive and other hydraulic functions to match site conditions and operator preference.

Optional toolbox

Optional undercarriage-mounted toolbox provides convenient storage for tools, saw teeth, additional saw bars, and other spare parts, minimizing trips back to the service truck.

FORESTSIGHTAlerts can be sent to your computer or mobile device — or your Deere dealer, if you choose — to inform you of immediate machine issues. If down-time does occur, exclusive remote diagnostics and programming enable your dealer to minimize the time and cost associated with sending a technician to the logging site for an initial diagnostic visit. You can also receive reminders of periodic scheduled maintenance on your computer or mobile device, or from your dealer.

More visibility, more profitability

TimberNavi is a proven jobsite-mapping solution designed for full-tree logging operations. It gives you in-machine visibility of current position, harvesting area, points of interest, and more. Alarm functionality gives operators increased awareness of cut-block boundaries and hazards, and a 10-in. high-resolution display makes the entire jobsite visible at a glance. By delivering accurate location information in real time, TimberNavi enables operators to navigate confidently and efficiently through the jobsite.

Simplified serviceability

Easy access to service components helps confirm daily checks and preventative maintenance get done on schedule, minimizing costly repairs down the road.

Hydraulic reversing fan

Standard variable-speed reversing fan runs only as fast as the system requires. This conserves power and fuel while blocking debris. To keep the system clean, the fan also reverses on a timed cycle to reverse airflow and eject debris from the cooling cores. If conditions demand more frequent cleaning, the fan can be reversed by a simple push of a button.

Proven components

800M- and 800MH-Series machines share many common components — including the engine, undercarriage, booms, and cab — with their 900M- and 900MH-Series counterparts, for ease of maintenance and repairs when needed.
